Abstract

The sorption of heavy metals (i.e. Pb and Cu) in soils from Selangor was investigated using batch equilibrium test (BET). The test was conducted in two systems, i.e. single and mix solutions. The sorption isotherms from BET were well described by the Langmuir equation which then used to calculate the sorption parameters, i.e. distribution coefficient (Kd) and maximum adsorption capacity (Am). The Langmuir sorption equation was chosen according to the experimental data that are fitted to the equation (i.e. based on their linear regression values, r2). The study has revealed that different soils have different sorption capacity for different heavy metals. The Kd values are proportional to the sorption capacity of soils. Soil with high sorption capacity possesses higher Kd value. The sorption of Pb and Cu in single solution is higher than in mix solution, due to competition for sorption sites among heavy metals in mix solution. The Kd values for Pb in single solution ranging from 36.18 - 334.48 L/g and for Cu is 9.29-66.19 L/g. In mix solution, the Kd values for Pb and Cu are smaller ranging from 23.13-31.79L/g and 3.95-18.53 L/g respectively.
